To (Ll/ 107mm 77/? may concur/t:

P16 it known that 1, VVTLLIAM B. \VA'rnns, a citizen of the United States, residing at Atlantic City. New Jersey, have invented certain new and useful improvements in Heaters for li ire-l lngines, oi which the following is a specification.

My invention relates to heaters for steam lire-engines, and particularly to a valve device which when the lire'engine leaves the engine-house will be automatically operated to cut 011 the How of fuel to the burner which is utilized for heating the water of the boiler of the engine during the time that the said engine is at rest in the engine-house.

The invention consists in the features and combination and arrangement of parts here inat'ter described, and particularly pointed out in the claim.

in the accompanying drawings. Figure 1 is a side view of a part of the steam lire-engine with my improvement attached. Fig. 2 is a sectional view of the automatic cut-otl valve for the fuel-supply.

My invention belongs to that class of apparatus which designed to heat the water of a lire-engine boiler while the engine is at rest within the engine-house, so that in case of iire the engine on leaving the engine-house will have its boiler containing hot water ready to make steam as soon as the iire is started in the furnace. 1

in the drawings, 1 represents the boiler of the lire-engine; 2, one of the carrying-wheels. Pipes 3 connect with the boiler and with a heating-coil 4:, arranged within a casing 5, supported in any suitable manner within the engine-house, to be lixed therein and to be disconnected from the engine when the same starts for the lire. The detachable connections lie in the pipes 3 and consist of slipjoints 6 of any well-known form provided with check-valves adapted to automatically close when the two parts of the pipes 3 are disconnected. Beneath the coil t is arranged a burner adapted to burn gas or other fuel, this burner being a fixture within the engine-house. The supply-pipe to the burner is indicated at 7, and in this pipe a coupling 8 is arranged containing ports 9, through which the Fuel passes from the pipe 7. A valve-chamber 10 ex tends transversely to the axes oi the said ports 9, and in this valve-chamber a valve 11 operates, this being in the form of a piston having a port 12 extendil'ig through it transversely and adapted to connect the ports 9 in the coupling or valvecasing. This pistonvalve is pivotally connected with a piston-mil 13, extending forwardly and count-acted to a lever 14:, pivoted to a suitable bracket on the floor oi the engine-house, the said lever extending upwardly and with its upper end arranged to be struck by the slmulder '15 of a part of the pipe 3. Normally the lever rests upon the said shoulder, and with the parts in this position the piston-valve is so positioned that its port is in line with the ports S) J and the fuel is free to pass through the 'alve-casing to the burner, and thusl rat the water in the coil 4, which beingconnccted through the pipes 3 with the boiler a circulation will be set up and the water of the boiler will be heated.

in answering an alarm as soon as the engine starts to move from the engine-house the slipjoints at 6 will be operated, disconnecting the parts. of the pipes 3 which are fixed to the engine from the portions of the said pipes which are connected with the coil 4, and the check-valves will then operate and automatically close to retain the water in the boiler. At the same time the lever 14: will beoperated and the piston-valve 11 will be drawn outwardly from its casing so that port 12 will come opposite a solid part 01'' the casing, and a solid portion of the piston-valve will now extend across the ports 9 9,and thus cut oil the fuel from the burner. and the parts will remain in this position until the engine is returned to the engine-house and proper connections are made by means of the slipjoints, when the parts may be readjusted and the burner lighted.

The burner may be of any suitable type, such as a Bunsen burner.

It will be noticed that the heating appara tus is entirely indepemlent of the engine, and the only parts that remain on the ei'igine are the portions of the circulating-pipes 3 connected therewith. The whole device is above the level of the floor, where it is readily accessible. The piston-valve, it will be noted, operates horizontally, and a direct connection extends therefrom to the lever.

1 claim as my invention In combination with a steam fire-engine, a heating device includinga burner circulatingpipes having slip-joint connections, a valve consisting of a piston operating horizontally in a casing and controlling the fuel-supply to l the burner, a connection extending horizonl tally from the said valve, a lever pivotally supported and extending upwardly to be eni gaged by apart carried by the engine, the 3 said lever being joined to the said horizontal 1 connection, substantially as described. i In testimony whereof I mix my signature in presence of two witnesses.
